Summary
The brain
Area of Science:
- Cognitive Neuroscience
- Visual Attention
- Oculomotor Control
Background:
- Brain regions controlling gaze are also used for spatial attention shifts.
- External attention and gaze control are linked, guiding eye movements to relevant locations.
- Internal attention can be directed to visual working memory without external targets.
Purpose of the Study:
- To investigate if the oculomotor system aids attention focusing within internal memory representations.
- To determine if gaze behavior reveals the oculomotor system's role in internal attention.
Main Methods:
- Participants selected items from visual working memory.
- Gaze behavior was monitored to detect any biases.
- The study analyzed the relationship between gaze bias and attentional focus.
Main Results:
- Selecting a visual working memory item biased gaze toward its memorized location.
- This 'gaze bias' occurred when the item was not the focus of attention.
- The gaze bias predicted performance benefits from internal attention focusing.
Conclusions:
- The oculomotor system participates in directing attention within memorized spatial representations.
- This internal attention focusing leaves detectable traces in gaze behavior.
- The eyes reflect the brain's internal attentional landscape.

The frequency-domain technique, commonly used in analyzing and designing feedback control systems, is effective for linear, time-invariant systems. However, it falls short when dealing with nonlinear, time-varying, and multiple-input multiple-output systems. The time-domain or state-space approach addresses these limitations by utilizing state variables to construct simultaneous, first-order differential equations, known as state equations, for an nth-order system.

1.3K
A space truss is a three-dimensional counterpart of a planar truss. These structures consist of members connected at their ends, often utilizing ball-and-socket joints to create a stable and versatile framework. The space truss is widely used in various construction projects due to its adaptability and capacity to withstand complex loads.
At the core of a space truss lies the fundamental unit known as the tetrahedron. This structure is composed of six members that form a three-dimensional shape...

State-space representation is a powerful tool for simulating physical systems on digital computers, necessitating the conversion of the transfer function into state-space form. Consider an nth-order linear differential equation with constant coefficients, like those encountered in an RLC circuit. The state variables are selected as the output and its n−1 derivatives. Differentiating these variables and substituting them back into the original equation produces the state equations.

The conversion of state-space representation to a transfer function is a fundamental process in system analysis. It provides a method for transitioning from a time-domain description to a frequency-domain representation, which is crucial for simplifying the analysis and design of control systems.
The transformation process begins with the state-space representation, characterized by the state equation and the output equation. These equations are typically represented as:

01:13Rocket Propulsion in Empty Space - I
3.8K
The driving force for the motion of any vehicle is friction, but in the case of rocket propulsion in space, the friction force is not present. The motion of a rocket changes its velocity (and hence its momentum) by ejecting burned fuel gases, thus causing it to accelerate in the direction opposite to the velocity of the ejected fuel. In this situation, the mass and velocity of the rocket constantly change along with the total mass of ejected gases. Due to conservation of momentum, the...
